This is the repository for code examples used in the public AWS documentation. The code examples are organized by programming language. You can also try using the preview of our use case index of examples and let us know what you think about it.

Inside each language-specific directory, we include a README file that explains how to build and run the examples in the directory. The example code in the language-specific directories is organized by the AWS service abbreviation s3 for Amazon S3 examples, and so on.

To propose a new code example for the AWS documentation team to consider working on, create a request. The AWS documentation team wants to produce code examples that cover broader scenarios and use cases, versus simple code snippets that cover only individual API calls. From time to time, the AWS documentation team will select some of these proposals to begin working on.

To view their decisions, see the code examples roadmap. The Wish List represents proposals that the team might begin working on sometime in the future, but with no expected timeline.

The Backlog stage represents proposals that the team will likely begin working on soon. To view the team's progress, see the code examples roadmap.

If you plan to contribute examples for use in the documentation the purpose of this repositoryread this section carefully so that we can work together effectively. For process instructions and additional guidance, see the Guidelines for contributing. Make sure that the code you want to contribute builds and runs.

There's nothing more frustrating in developer documentation than code examples that don't work. Build the code and test it before submitting it! Don't include personal account data, keys, or IDs in your examples. Code should obtain access keys from the standard SDK credentials and config files, use environment variables or external data files, or query the user for this information. Format code lines to 80 characters. Long lines can be enclosed in a scrollable box for HTML, but in a PDF build, long lines often spill off the side of the page, making the code unreadable.

If your code includes long text strings, consider breaking these into smaller chunks and concatenating them. Use short er variable names. To aid in readability and to help keep line length to 80 characters, use short yet descriptive names for variables.

Do not mimic class names when creating variables that represent an object of that class. It nearly always results in excessively long variable names, making it difficult to keep code lines to 80 characters. Use spaces, not tabs, for indentation. Tabs are variable length in most editors, but will usually render as 8 characters wide in printed documentation.

Always use spaces to ensure consistent formatting in printed code. You can ignore this rule for makefiles, which might require the use of tabs. But these are typically used only for building examples, and aren't included in documentation. Minimize the use of comments. Code is ignored for translation, so comments in code aren't translated for the printed documentation's target language.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

Right now I am using the javascript SDK to access my s3 bucket and it works fine but I have hard-coded all my credentials in the javascript directly but in the SDK they are saying you can store these in the AWS.

Also, the online resources are not informative so can someone please let me know how to do this or any other better way to do this instead of hard-coding the credentials?

You can do that by creating the file or using aws configure with the cli command, answer the questions and it will generate this file:. I believe this is not supported in the browser.

On a different note, why not expose the S3 bucket publicly for read access since the javascript on the browser is public anyways? There is a way to achieve JS uploads in the browser without revealing your private credentials.

It does however, require some server side logic. See answer here: S3 upload directly in JavaScript.

Rico Rico My understanding, correct me if I'm wrong, is that authorization can be on a per-identity basis, and session keys are generated for logins that are attached to IAM roles, and that the system is "secure enough" because these keys are passed over HTTPS, locked to the domain, and expired.

Those services are accessed via a web management console, which is a web application that allows the management of the AWS services using a rich and interactive UI.

Those credentials could be reused by any application user to consume the same services, allowing them to enjoy free services. At the end of Amazon provided the ability for client-side JavaScript developers to create web applications without the need to have a backend server or to configure an application server for hosting. More details about this part will be given in the following section. In this article, I will introduce this new architecture and explain the step-by-step workflow to prepare the environment and consume one of the AWS services from a browser-based app.

As mentioned in the introduction, using the new JavaScript SDK in the browser, a web app could be developed without any need to a server side backend. The new, two-tier architecture contains a third party, the Web Identity Federation, where the application user will authenticate and, after that, provides an access token to the user. It can be considered as a Kerberos Serverwhereby the architecture and workflow will be as follows :. It did not use a temporary access token, so the new architecture could be considered more secure than the old one, due to the fact that the credentials are not used within the whole app code.

Before we start writing any code, we first need to prepare and configure the environment by creating an app ID in the Web Identity Federation side, create a role, configure permissions for this role in the AWS IAM side console, and assign the app Client ID to the created role to establish the connection between the two parts:.

Go to the Credentials item in the left menu and create a new client ID for web application. In the authorized JavaScript origin set the name of your computer along with the port number, e. Open the IAM console herego to the left menu, click on Roles item and click on Create new role button to start the the creation steps.

Once this is complete, click on Role for Identity Provider Access radio button :. Next, select the identity provider from the drop down list and enter the client ID in the audience text input and click on continue:. Take a look to this doc for more details. We can edit the permissions document manually or by using the policy generator and entering the Amazon Resource Name ARN :.

If we compare it with the configuration and deployment of a web app with a backend server, it could be considered a time and money saving process. To load the SDK in the browser, we simply need to add the following script tag:. The getAccessToken function will use the following code to authenticate the web user and get a temporary access to AWS services:.

The serviceUser object should be declared at the top of the page. This object will be used afterwards to authenticate the user in the AWS service. To authenticate our application on the AWS side, we should use the ARN Amazon Resource Name that we have received when preparing the environment, and the serviceUser variable that we filled in the previous section.

The SDK keeps the same methods and properties, making the code migration very simple from server side to client side. For more details about how to create the web identity credentials, take a look at this AWS doc. Finally, and after preparing the environment and configuring the web identity credentials, we can now load the AWS services objects and consume the services from our app.Welcome to our resources for Cognito developers.
